On Printer Storage for Microfiber Build Plate Cleaner

For years I'd been burning my fingertips cleaning hot build plates by hand with isopropyl alcohol and paper towel.  A short time ago, my friend TravisT https://www.printables.com/@TravisT_1216398 introduced me to K-Studio.ca's bed cleaner https://www.printables.com/model/815732-build-plate-cleaner-microfiber-holder

I finally got around to printing it and trying it out a few weeks ago.  It works well, and my burnt fingertips are just starting to heal from all those years of abuse.  :)  I know there are a few vertical holders for K-Studio.ca's model floating around, but I wanted a quick easy way of mounting a holder horizontally on a 40x40 or 20x40 aluminum extrusion, so I made this.

It prints easily as oriented in the STL without needing supports, and attaches to the top of a 40x40mm or 40x20mm aluminum extrusion printer frame with two M4 X 8mm button head screws and two M4 T-Nuts.
